(Outline of gaming machine)

  The gaming machine in the present embodiment is a slot machine 10 including a controller that executes a slot game in which a plurality of symbols 501 are rearranged to obtain a game result as a base game. The slot machine 10 has a reel assembly M11 that supports a plurality of reels M3 to which a plurality of symbols 501 are attached, and after the plurality of reels M3 are rotationally driven, the slot machine 10 stops and then rearranges the plurality of symbols 501. Executed.

  Specifically, as shown in FIGS. 1 to 3, the reel assembly M11 includes a reel M3 provided with a reel band M32 to which a plurality of symbols 501 are attached, a backlight device M7 that illuminates the reel M3 from the inside, It has. The reel band M32 includes a base material layer M320, a symbol print layer M322, and a mesh pattern layer M321. The base material layer M320 has translucency. The symbol print layer (symbol layer) M322 is stacked on the outer side in the layer thickness direction of the base material layer M320 to form a plurality of symbols 501. The mesh pattern layer M321 is laminated in a region different from the region (symbol formation region M3210) where at least a plurality of symbols 501 are formed on the base material layer M320 when viewed in the lamination direction, and is formed in a textured shape. That is, the mesh pattern layer M321 includes a shielding region M3211 that attenuates light from the backlight device M7 and an unstacked region M3212 that transmits light from the backlight device M7 to the outside. The backlight device M7 is controlled to be turned on and off by the controller 100 that rearranges the plurality of symbols 501.

  Further, on the innermost layer of the reel band of the reel assembly M11, a concave member M331 which is formed in a concave shape in cross section, has translucency, and forms an internal space with the inner wall surface and the reel band M32, and the inner wall surface A concave three-dimensional molding part M330 having a three-dimensionally formed transparent symbol M332 is provided.

  Here, the “texture shape” indicates that the mesh pattern layer has a texture in which an uneven pattern is formed on the surface by the shielding region M3211 and the non-laminated region M3212. The mesh pattern is not limited, and may be a repeated pattern of the same pattern such as a striped pattern, a lattice pattern, a honeycomb structure, and a punching mesh structure, or a lace pattern, a ribbon pattern, and a flower pattern. Such a repeating pattern may not be used, or a combination thereof may be used.

  Thus, the symbol print layer M322 attached to the reel band M32 is illuminated by the light from the backlight device M7 that passes through the base material layer M320, and a plurality of symbols 501 are visually recognized from the outside. In addition, regarding the symbol formation region M3210 in which a plurality of symbols are not formed, the light transmittance from the backlight device M7 can be adjusted by the area ratio of the shielding region M3211 and the non-stacked region M3212. Further, the mesh pattern layer M321 is illuminated by the backlight device M7, whereby a pattern formed by the shielding area M3211 and the non-stacked area M3212 is highlighted in an area other than the symbol 501 of the reel M3, and decoration not based on printing is applied. Can do. That is, light from the backlight device M7 is shielded in the shielding region M3211, and light from the backlight device M7 is transmitted in the non-stacked region M3212. Therefore, it will be visually recognized so that the pattern of the shielding area M3211 may be raised.

  Further, when the backlight device M7 is turned off, the internal space of the concave member M331 has an external illumination with a transmittance adjusted according to the area ratio of the shielding region M3211 and the non-laminated region M3212 in the mesh pattern layer. Therefore, the inner space of the concave member M331 becomes darker than the outside of the reel M3. Therefore, the transparent symbol M332 formed in the internal space is in a state where it cannot be viewed from the outside or is difficult. On the other hand, when the backlight device M7 is lit, the internal space of the concave member M331 is illuminated with light from the backlight device M7, so that the transmissive symbol M332 in the internal space is visually recognized through the reel band M32. It becomes possible. Therefore, as a result, even a mechanical reel can be mounted with a symbol that can be switched between display and non-display on the reel.

  In this embodiment, the mesh pattern layer M321 is laminated on the base material layer M320 by screen printing, offset printing, or the like. Thereby, the adjustment of the transparency of the reel can be realized more easily. The mesh pattern layer M321 is not limited to this, and the mesh pattern layer M321 may be one in which a wire net, punching metal, cloth such as hemp, lace, ribbon, or the like is attached to the base material layer M320. In that case, you may provide the adhesive bond layer which adhere | attaches the mesh pattern layer M321 and the base material layer M320. When providing the adhesive layer, it is preferable to use a permeable resin.

  Further, the shielding region M3211 is not limited to being stacked with a member that does not transmit light, and it is sufficient that at least light from the backlight device M7 is attenuated. Moreover, when providing the illuminating device which illuminates the reel M3 from the outside, it is preferable to make the light quantity of the transmitted light from the backlight apparatus M7 larger than the light quantity of this illuminating device. Thereby, the visibility of the transparent symbol M332 is improved.

  In the present embodiment, the gaming machine is the slot machine 10 intended for a single player, but a multi-participant model including a plurality of slot machines 10 may be used. That is, the gaming machine is a multi-participant type, and may include a plurality of slot machines 10 and a center controller connected to the plurality of slot machines 10 so as to allow data communication. Thereby, the gaming machine can execute a base game such as a slot game individually in each slot machine 10 and can execute a common game in synchronization with each slot machine 10. As described above, the slot machine 10 can also be applied as a game terminal of a gaming machine. In this case, the connection between the slot machine 10 and the center controller may be either wired or wireless, or a combination thereof. The unit of the bet amount may be a currency of a country or region such as dollars, yen, euro, or a game point used only in a hall or industry equipped with a gaming machine. Further, the symbol 501 may be singular or plural and may be one or more. The symbol 501 may be formed on the entire circumference of the reel M3 or may be formed on a part of the entire circumference.

  The rearrangement of the symbols 501 in the slot game is performed in a reel device M1 (symbol display device) controlled by the controller 100. In the slot game, on the condition that a gaming value is bet, the symbols 501 are rearranged in the reel device M1, and a normal game for giving a normal payout according to the rearranged symbols 501 is executed.

Have.

  The “symbol 501” is not limited to the type and the number as long as it is rearranged in the reel device M1, but is a superordinate concept of a specific symbol and a normal symbol. The specific symbol is added to the normal symbol as necessary. For example, the specific symbol includes a wild symbol and a trigger symbol. The wild symbol is a symbol that can be used as a symbol 501 of any kind. The trigger symbol is a symbol serving as a trigger for starting execution of at least the bonus game. For example, in this embodiment, “chance cherry” corresponds. The trigger symbol may be a trigger that increases the specific symbol in the bonus game, that is, increases the specific symbol of at least one of the trigger symbol and the wild symbol. The trigger symbol may be a trigger that increases the number of bonus games in the bonus game.

  The “game value” is a coin, a bill, or electronic valuable information corresponding to these. The game value in the present invention is not particularly limited, and may be a game medium such as a medal, token, electronic money, ticket or the like. The ticket is not particularly limited, and may be, for example, a ticket with a barcode described later.

  “Bonus game” is synonymous with feature game. The bonus game in the present embodiment has been described as a game in which a free game is repeated. However, the bonus game may be any type of game as long as the game state is more advantageous than the normal game. In addition, other bonus games may be adopted as long as the game state is advantageous to the player, that is, the game state is more advantageous than the base game. For example, the bonus game has various states such as a state in which more game values can be obtained than a normal game, a state in which game values can be acquired with a higher probability than a normal game, and a state in which the number of game values consumed is less than in a normal game. May be realized alone or in combination.

  A “free game” is a game that can be executed with fewer bets of game value than a normal game. “A game can be executed with fewer bets of game value” includes the case where the bet is “0”. Therefore, the “free game” may be a game that is executed without a game value betting condition and pays an amount of game value corresponding to the rearranged symbols 501. In other words, the “free game” may be a game that is started without presuming the consumption of game value. On the other hand, the “normal game” is a game that is executed on the condition that a game value is bet and pays an amount of game value corresponding to the rearranged symbols 501. In other words, the “normal game” is a game that is started on the premise that the game value is consumed.

  The “rearrangement” means that the symbol 501 is rotated and then stopped and displayed. In other words, the symbol 501 is arranged again after the symbol 501 is released. “Arrangement” means that the symbol 501 can be visually confirmed by an external player.

  “Normal payout according to rearranged symbols 501” means a normal payout corresponding to the rearranged winning combination. The “bonus payout according to the rearranged symbols 501” means a bonus payout corresponding to the rearranged winning combination. The “winning combination” means that a prize is established.

  “Conditions that result in a payout rate larger than that of the base game” include execution of a free game, increase of wild symbols and trigger symbols, execution of a game using a replaced symbol table, and the like.

  Specifically, the irradiation light device R1 includes a translucent panel R11 (a translucent member) provided in the opening 1343a of the panel support 1343, and a light source R12 that emits outside illumination light. The translucent panel R11 is provided so that the light source R12 and the outside illumination light from the light source R12 do not directly enter the player's field of view. The translucent panel R11 has a width dimension substantially equal to the width of the reel device M1. The light source R12 is formed so as to emit outside illumination light over the entire width of the translucent panel R11.

  The light source R12 has a plurality of full-color LEDs R121. The full-color LEDR121 is a single light-emitting source using chips of red, green, and blue light-emitting diodes that are the three primary colors of light. By adjusting the light quantity of each color LED, illumination light of any color can be obtained. Can be formed. These full-color LEDs R121 are arranged in a matrix in the width direction and the depth direction. Specifically, as shown in FIG. 4, the light source R12 includes an LED unit R123 in which two full-color LEDs R121 arranged in two rows and two columns are arranged in the width direction of the reel strip M32. The unit R123 is arranged so as to correspond to each reel M3. Thereby, the irradiation position to the reel device M1 can be adjusted by controlling the lighting position of the full color LED.

(Display mode of display window 150)
A display mode of the display window 150 by configuring the reel band M32 as described above will be described.

(Display mode of reel band M32)
As shown in FIG. 15, the reel band M32 is illuminated from inside and outside by illumination light from the backlight device M7 and the irradiation light device R1. At this time, in the reel band M32, the illumination light from the backlight device M7 and the irradiation light device R1 is adjusted according to the area ratio between the shielding region M3211 and the non-stacked region M3212 in the mesh pattern layer M321. In other words, the illumination light traveling from the backlight device M7 toward the player is partially blocked by the shielding region M3211, and mitigates the situation where the inner illumination light travels directly to the player. Further, a part of the illumination light that illuminates the reel band M32 from the irradiation light device R1 is transmitted by the non-stacked region M3212, so that the outside illumination light is directly reflected to the player. As described above, the area ratio between the shielding region M3211 and the non-stacked region M3212 without using a conventional sheet for suppressing the transmittance of the illumination light in the region where the plurality of symbols 501 are not formed. Can be adjusted.

  In addition, a textured pattern by the mesh pattern layer M321 emerges on the reel band M32. That is, the illumination light from the irradiation light device R1 and / or the backlight device M7 does not pass through the shielding region M3211 (or part of the irradiation light is shielded) in the mesh pattern layer M321, and the non-laminated region M3212. A textured shadow pattern emerges by passing through the screen. In this way, the reel band M32 can be decorated without using the conventional decoration by image printing. Since the shielding region M3211 is three-dimensionally stacked on the base material layer M320, even when there is no illumination light, a textured texture can be given to the reel band M32.

(Display mode of reel band M32: concave three-dimensional molding part M330)
Next, the display mode of the display window 150 in the place where the concave three-dimensional molding part M330 is provided will be described.
As shown in FIG. 16, when the irradiation light device R1 is turned on and the backlight device M7 is turned off, the inside of the internal space M333 formed by the reel band M32 and the concave member M331 is more than the outside of the reel band M32. Get dark. That is, a part of the outside illumination light from the irradiation light device R1 is blocked by the mesh pattern layer M321 of the reel band M32, so that the transmission symbol M332 provided in the internal space M333 is visually recognized through the reel band M32. Inability to view or difficult to see (hereinafter, this state is referred to as a transparent symbol non-display state).

  Next, as shown in FIG. 17, when both the irradiation light device R1 and the backlight device M7 are lit, the interior space M333 formed by the reel band M32 and the concave member M331 becomes bright. That is, the transparent symbol M332 provided in the internal space M333 is in a state that is easier to visually recognize than the transparent symbol non-display state via the reel band M32 (hereinafter, this state is referred to as a transparent symbol display state). Therefore, the transparent symbol M332 is visible in the display window 150.

  As described above, when the backlight device M7 is turned off, the inner space M333 of the concave member M331 has a transmittance adjusted by the ratio of the area of the shielding region M3211 and the non-stacked region M3212 in the mesh pattern layer M321. Since transmitted light from outside illumination or the like is irradiated, the internal space M333 of the concave member M331 becomes darker than the outside of the reel device M1. Therefore, the transparent symbol M332 formed in the internal space M333 is in a state where it cannot be viewed from the outside or is difficult. When the backlight device M7 is turned on, the internal space M333 of the concave member M331 is illuminated by the backlight, so that the transmissive symbol M332 is visible from the outside. As a result, even a mechanical reel can be mounted with a symbol that can be switched between display and non-display on the reel.

In the present embodiment, as described above, the transmissive symbol M332 has translucency and is colored. Therefore, by illuminating the illumination light emitted from the backlight device M7 with the same color or the same color as the color of the transmissive symbol M332, the transmissive symbol M332 is not displayed on the display window 150 (not visually recognized or visually recognized). It can be difficult). Further, the light intensity of the outer illumination light from the irradiation light device R1 is made stronger than the inner illumination light of the backlight device M7, and by contrast, the brightness of the internal space M333 is darkened so that the transmission symbol M332 is not displayed ( (It is not visually recognized and difficult to be visually recognized). Thus, the transparent symbol non-display state may be a state in which the transparent symbol M332 in the internal space M333 is less visible than the transparent symbol display state.
In addition, when the illumination light emitted from the backlight device M7 has a color that is complementary to the color of the transmission symbol M332, the transmission symbol M332 can be displayed more easily.

(Game program processing)
FIG. 19 is a block diagram showing processing of a game program executed by the main CP 71 of the motherboard 70. When power is supplied to the slot machine 10, the main CP 71 reads the authenticated game program and game system program from the memory card 54 via the gaming board 50, and writes these programs in the RAM 73. The game program is executed in the state loaded in the RAM 73 in this way.

  According to a preferred embodiment, the game program includes an input / bet check process P300, a random number generation process P302, a symbol determination process P304, a game counter, a reel control process P308, a winning determination process P310, and an effect generation. A control process P312, a payout process P314, and a game mode determination process P316 are included.

(Input / bet check processing P300)
The input / bet check process P300 continues whether or not either the “BET” button or the “START” button is pressed in the idle state in which the reel M3 of the first to fifth reel assemblies M11a to M11e is stopped. Check it. When the “BET” button 601 or the spin button 602 (start button) is pressed, the input / input / bet check process P300 determines whether or not the player's credits remain based on the credit data 320 stored in the RAM 73. To check. When at least one credit of the player remains, the input / bet check process P300 calls the random number generation process P302.

  Thereafter, the random number generation process P302 generates a random number and uses the random number in the symbol determination process P304. In the present embodiment, the random number generation process P302 generates five random numbers. Each of the five random numbers is used for each of the reels M3 of the first to fifth reel assemblies M11a to M11e.

  After all five random numbers have been extracted, the symbol determination process P304 refers to the symbol code determination table stored in the RAM 73 to determine the symbols to be stopped on each reel M3. The symbol determination process P304 uses five random numbers to determine five symbols to be stopped on the reel M3, and each of the reels M3 of the first to fifth reel assemblies M11a to M11e in the display window 150 of the reel device M1. To make the stop scheduled symbol appear.

  In particular, the symbol determination process P304 refers to the mode flag 322 stored in the RAM 73 to check the current game mode. The process for determining a symbol in the normal mode is different from the process for determining a symbol in the chance mode. In the normal mode, the symbol determination process P304 determines a symbol using a random number according to a certain procedure using a certain symbol code determination table. On the other hand, in the chance mode, the symbol determination process P304 continuously changes the symbol code determination table for each unit game, and changes the symbol determination process. By continuously changing the symbol code determination table, the winning combinations including at least one specific symbol can be increased as the chance mode game continues. The number of chance mode games that can be executed in a single session is limited to a predetermined number, for example, eight. In order to limit the number of chance mode games, the game counter 306 counts the number of chance mode games already executed in the session and the number of chance mode games remaining in the session. The game count value is stored in the RAM 73. The game counter may belong to the symbol determination process P304.

  The reel control process P308 controls the reel device M1 by supplying stop position information corresponding to the determined symbol. In this way, each reel M3 of the first to fifth reel assemblies M11a to M11e rotates and then stops at the position specified by the stop position information. That is, the symbols scroll with the rotation of each reel M3. Next, each reel M3 is stopped so that the determined symbol is rearranged at the center position in the vertical direction in the display window 150 of the reel device M1.

  The winning determination process P310 determines whether or not a predetermined winning combination is established by the rearranged symbols. When the winning combination is established by the rearranged symbols, the effect generation control process P312 controls the reel device M1 and other devices. Other devices include a speaker 112, a lamp, an upper image display panel 131, and the like. Production includes production by video and audio, production by backlight change and illumination. In addition, the payout process P314 determines a payout amount according to the established winning combination, and gives the payout amount to the player.

  Each time the unit game ends, the game mode determination process P316 determines the game mode of the next unit game. When a trigger event occurs due to the rearranged symbols, the game mode determination process P316 changes from the normal mode to the chance mode. On the other hand, when the end condition is satisfied, the game mode determination process P316 changes from the chance mode to the normal mode. In other cases, the game mode determination process P316 maintains the previous game mode. The game mode determination process P316 may be executed in the winning determination process P310.

(Symbol, winning combination, and payline)
FIG. 20 shows an example of a symbol code table that defines symbols attached to the outer peripheral surface of each reel M3 of the first to fifth reel assemblies M11a to M11e.

  A symbol column composed of 11 symbols is formed by the symbols attached to each of the reels M3. As will be described later, the arrangement of symbols assigned to each of the reels M3 is referred to as first to fifth symbol columns, respectively. In the present embodiment, the symbol string includes six types of symbols. The six types of symbols are “7”, “BAR”, “2 BARs”, “3 BARs”, “Cherry”, and “Chance Cherry”. In each symbol row, codes from “00” to “10” are assigned to each symbol. For example, the code “00” is assigned to the first symbol “BAR” of the first symbol column. The code “01” is assigned to the second symbol “7” of the first symbol row. The code “07” is assigned to the eighth symbol “7” of the first symbol column.

  A 3 × 5 symbol matrix can be formed in the display window 150 by causing three consecutive symbols of each of the symbol columns to appear in the display window 150 of the reel device M1. Each time the “BET” button or the “START” button is pressed, the reel M3 to which the symbol is attached starts rotating, and the symbol 501 appears in the display window 150 so that the symbol 501 is scrolled vertically in the display window 150. . After a predetermined time has elapsed, the scrolling of the symbols 501 is stopped, the symbols are rearranged, and a symbol matrix is formed in the display window 150.

<"Chance Cherry"symbol>
The “chance cherry” symbol that appears only in the third symbol row functions as a trigger symbol that shifts the game mode to the chance mode. In this embodiment, the “chance cherry” symbol has a shape similar to the “cherry” symbol, but is composed of an image in which a cherry image and a background image of a flame surrounding the cherry are integrated. The As shown in FIG. 21, after the “chance cherry” symbol appears in the second row and third column in the display window 150 due to the rearrangement of symbols, the chance mode starts. The conditions for returning the game mode to the normal mode will be described later.

  A plurality of types of winning combinations of symbols (hereinafter referred to as “winning combinations”) for giving a profit to the player are predetermined. The profit given to the player includes a predetermined amount of payout by increasing credits or paying out coins.

  FIG. 22 shows the paylines defined in the preferred embodiment of the present invention. In the present embodiment, five paylines are set for the symbol matrix. The first to third paylines extend in the horizontal direction and extend across the symbol stop positions of the first to third rows of the symbol matrix, respectively. The fourth payline has a symbol stop position in the first row and first column, a symbol stop position in the second row and second column, a symbol stop position in the third row and third column, and a symbol in the second row and fourth column. It extends in a “V” shape connecting the stop position and the symbol stop position of the first row and the fifth column. The fifth payline has a symbol stop position in the third row and first column, a symbol stop position in the second row and second column, a symbol stop position in the first row and third column, and a symbol in the second row and fourth column. It extends in an “inverted V” shape connecting the stop position and the symbol stop position in the third row and fifth column.

  Each of the paylines can be activated in response to player selection. However, all five paylines can be activated regardless of bet amount or player selection. The total number of paylines can be changed according to the size of the symbol matrix, and other paylines can be set as appropriate.

(Game mode (normal mode and chance mode))
The slot machine 10 selectively executes two modes (normal mode and chance mode). Game processing in the chance mode is almost the same as in the normal mode. However, the payout for at least some of the winning combinations in the chance mode is different from the payout in the normal mode. In addition, it is possible to make different effects such as a video effect and a sound effect in the two game modes. In this specification, a unit game executed in the normal mode may be simply referred to as a normal mode game. Similarly, a unit game executed in the chance mode may be simply referred to as a chance mode game.

(Game state transition)
FIG. 23 is a state transition diagram of the slot machine 10.

  In the slot machine 10, the game mode is normally in the normal mode, and the normal mode is maintained unless a trigger event occurs. When the trigger event occurs during the normal mode, a state transition occurs in which the game mode shifts to the chance mode. In the preferred embodiment, the trigger event is the occurrence of the “Chance Cherry” symbol at the position of the second row and third column of the symbol matrix.

  When the game mode shifts to the chance mode, the slot machine 10 maintains this state unless the end condition is satisfied. In the exemplary embodiment, one of the end conditions is that one of the winning combinations including “7” symbols is established. Another termination condition is that the “cherry” symbol of the symbol matrix formed by the rearranged symbols appears on one of the paylines. On the other hand, after the game mode shifts to the chance mode, the slot machine 10 sets a game counter that counts up or down every time a unit game in the chance mode is executed. The maximum number of unit games in the chance mode is 8 in a single chance mode session. Here, the term “chance mode session” means a period or state from when the game mode shifts to the chance mode (when the chance mode starts) until the end. Therefore, when the game counter value reaches 8 as a result of counting up, or when the game counter value reaches 0 as a result of counting down, the slot machine 10 is rearranged so as to satisfy the end condition. The “cherry” symbol appears in the symbol matrix formed by the formed symbols, or one winning combination composed of “7” symbols is established. For example, in such an operation, a process for determining a symbol combination is repeatedly executed until a symbol combination satisfying the end condition is obtained. When the end condition is satisfied, the game mode is returned to the normal mode, and the unit game in the normal mode is resumed.

(Symbol code determination table and payout table)
Regardless of the game mode, a combination of symbols (for example, including a combination of symbols to be stopped) is determined based on a plurality of tables stored in the RAM 73 of the motherboard 70. As described above, the RAM 73 stores at least one of a symbol code determination table and / or a symbol determination table.

  FIG. 24 shows an example of the configuration of the symbol code determination table.

  The symbol code determination table 340 to 348 stores the mapping relationship between the random number generated by the random number generation process P302 and the symbol code indicating each symbol shown in FIG. That is, every time a random number is generated by the random number generation function 302, the symbol determination process P304 refers to the symbol code determination tables 340 to 348 to determine a symbol code corresponding to one symbol. When the range of random numbers is widened, the probability that a symbol corresponding to the widened range is determined increases. In addition, when the entire range of random numbers is widened, the probability that a symbol code is determined can be controlled more accurately.

  In the symbol code determination tables 340 to 348, the table 340 is used to determine symbols in the normal mode, and the tables 341 to 348 are used to determine symbols in the first to eighth chance mode games, respectively. Used.

  When the first to fifth symbol columns are different from each other, each of the symbol code determination tables 340 to 348 may be further divided into five tables corresponding to the respective symbol columns. Further, as shown in FIG. 25, all the tables may be combined into a single table having 45 data fields. In the symbol determination process P304, one of the 45 data fields can be selected and used according to the game mode and the symbol string. In this specification, each of the 45 data fields can be viewed as a separate table.

  When two or more symbol sequences are the same as each other, a symbol in the symbol sequence can be determined using a common symbol code determination table. For example, in the example of FIG. 20, the second symbol sequence has the same symbol arrangement as the fourth symbol sequence. Therefore, the symbol code determination table of the second symbol sequence can be used to determine the symbols in the fourth symbol sequence. Similarly, the first symbol column has the same symbol arrangement as the fifth symbol column. Therefore, the symbol code determination table of the first symbol sequence can be used to determine the symbols in the fifth symbol sequence.

  When the symbol determination processing P304 determines five symbols for a predetermined row (for example, the second row) of the symbol matrix and all symbols constituting the symbol matrix are determined, the winning determination processing P310 determines which of the winning combinations. The game mode determination process P316 determines the game mode of the subsequent unit game.

  FIG. 26 shows an example of a symbol determination table. The symbol determination tables 360 to 368 define the probability that each symbol appears on the payline. The symbol code determination tables 340 to 348 shown in FIG. 24 can be determined based on the symbol determination tables 360 to 368. In the symbol determination tables 360 to 368, the symbol determination table 360 is used for the normal mode, and the symbol determination tables 361 to 368 are used in the first to eighth chance mode games, respectively.

  Similarly to the symbol code determination tables 340 to 348, each of the symbol determination tables 360 to 368 may be divided into five tables each corresponding to a symbol column. Furthermore, all the tables can be combined into a single table with 45 data fields as well.

  The probability that each symbol appears on the payline affects the probability that a winning combination is established. Conversely, the symbol determination tables 360 to 368 can be generated based on the winning combination probabilities. As in the payout tables 380 to 388 shown in FIG. 27, the relationship between the winning combinations and the respective probabilities can be summarized. The payout tables 380 to 388 define winning combinations together with respective payouts. The payout tables 380 to 388 are separately defined for the normal mode game and the chance mode game. In particular, it is preferable to separately define a payout table for use in eight unit games in the chance mode. In the payout tables 380 to 389, the payout table 380 is used for the normal mode game, and the payout tables 381 to 388 can be used for the first to eighth chance mode games, respectively. All payout tables 380-388 can be combined into a single table as well.

  Each time a unit game is executed, a winning determination process P310 included in the game program and executed by the main CP 71 determines whether or not a winning combination is established on the payline. When the winning combination defined in the payout table 380 to 388 is included in one of the paylines, the winning determination process P310 detects the winning combination and refers to the payout table 380 to 388 to determine the payout amount. To check. The payout process P314 pays out the determined payout amount. However, if the winning combination is not established by the symbols appearing on the payline, it is determined that the so-called losing.

  For example, if three “7” symbols appear along one of paylines LINE1 to LINE5 across a symbol string, it is assumed that three “7” winning combinations are established, and 200 times the bet amount is obtained. Payout as a payout amount. The profit by payout is given to the player by actually paying out coins to the coin tray 92 or adding an amount of credits.

(Probability of winning in chance mode)
As described above, when the “chance cherry” symbol appears at the position of the second row and the third column of the symbol matrix, the game mode shifts to the chance mode, and the chance mode is maintained until the end condition is satisfied. . The end condition is that one of the winning combinations composed of “7” symbols is established, or that the “cherry” symbol of the symbol matrix formed by the rearranged symbols appears on one of the paylines.

  When the game mode shifts to the chance mode, the counter process P306 shown in FIG. 19 displays a counter for counting the number of unit games in the chance mode already executed in the chance mode or the number of unit games to be executed in the chance mode. Set. After that, the random number generation process P302 generates a random number, and the symbol determination process P304 refers to the symbol code determination tables 341 to 348 to determine a stop scheduled symbol using the generated random number. The symbol determination process P304 uses the symbol code determination table 341 in the first (first) chance mode unit game. As the chance mode game progresses, the next symbol code determination table is used in order. When the 8th unit game (the last unit game in the chance mode in the present embodiment) is continued in the chance mode, the symbol determination process P304 ends the symbol combination (for example, the combination of symbols to be stopped). If the condition is not satisfied immediately, the process of determining the symbol combination is repeatedly executed until a symbol combination that satisfies the end condition is obtained.

  The probability that a winning combination is established depends on the symbol code determination tables 341 to 348. In particular, as the chance mode continues, the probability that a winning combination including a specific symbol is established increases. The symbol code determination tables 341 to 348 have mapping data between random numbers and symbol codes. The mapping data is data that more frequently establishes a combination related to a specific symbol as the chance mode continues.

  In the present embodiment, the specific symbol is a “7” symbol. That is, as the chance mode continues, the probability that a “7” symbol appears in a symbol matrix or a combination of symbols increases. The probability that the “7” symbol that is a specific symbol appears can be higher than that in the normal mode. Another symbol such as a “cherry” symbol may also be used as a further specific symbol. In the following description, both the symbols “7” and “Cherry” are used as specific symbols.

  FIG. 28 shows a table in which the probability of a winning combination associated with a specific symbol increases. As shown in the table on the right side of FIG. 28, the probability that three “7” winning combinations are established increases as the chance mode game continues. In other words, the probability of the combination of three “7” s in the second unit game is higher than that in the first unit game. The probability of the third unit game is higher than that of the second unit game. In this way, until the last (eighth) unit game is reached, the probability that three “7” winning combinations are established gradually increases. The same applies to the winning combinations of four “7” and five “7”.

  As a result, the total probability of the winning combination associated with the “7” symbol increases as the chance mode game is repeated. In the illustrated example, the probabilities of the combination of three “7”, four “7”, and five “7” are 1 / 32.8, 1/1, respectively, in the first (first) chance mode game. 67.2 and 1 / 672.0. As described above, the total probability of the combination related to the symbol “7” is 1 / 21.7 (= 1 / 32.8 + 1 / 67.2 + 1 / 672.0) in the first chance mode game. The total probability increases to 1 / 18.7 in the second unit game and continues to increase to 1 / 1.1 in the eighth unit game.

  The same is true for the winning combination probability associated with the “cherry” symbol. In order to entertain the player, the total probability of the winning combination associated with the “cherry” symbol is set to zero in the first (first) unit game, and the probability increases as the unit game progresses. In particular, the total probability of the winning combination associated with the “cherry” symbol is 1 / 10.4 in the second unit game and 1 / 6.6 in the third unit game. After the probability increases continuously, the total probability of the winning combination associated with the “cherry” symbol reaches 1 / 1.5 in the eighth unit game.

  The total probability of winning combinations associated with the “7” symbol and the “cherry” symbol is 1 / 21.7 in the first (first) unit game. Thus, after the first unit game, the probability that the chance mode will end is approximately 4.61% (= 1 / 21.7), and the probability that the chance mode will continue is 95.39% (= 1−1). 1 / 21.7).

  In the second unit game, the total probability of the winning combinations associated with the “7” symbol and the “Cherry” symbol is as high as 1 / 6.7 (= 1 / 10.4 + 18.7). Therefore, after the second unit game, the probability that the chance mode will end is about 14.95% (= 95.39% × 1 / 6.7), and the probability that the chance mode will continue is 85.05%. (= 95.39% × (1-1 / 6.7)). In the third unit game, the total probability of the winning combinations associated with the “7” symbol and the “Cherry” symbol is as high as 1 / 4.6 (= 1 / 6.6 + 15.1). Therefore, after the third unit game, the probability that the chance mode will end is about 21.73% (= 85.05% × 1 / 4.6), and the probability that the chance mode will continue is 78.27%. (85.05% × (1-1 / 4.6)).

  In the last (eighth) unit game, the total probability of winning combinations associated with the “7” symbol and the “Cherry” symbol is as high as 1 / 1.0 (= 1 / 1.5 + 3.1). . Therefore, the probability that the chance mode ends is 100% after the eighth unit game. When the eighth unit game is reached, the random number generation process P302 and the symbol determination process P304 repeatedly generate random numbers and determine symbols until a winning combination is established.

(Slot machine operation)
The operation of the slot machine 10 will be described with reference to FIGS.

  In the following description of the operation, one stop table among a plurality of stop tables is randomly determined at the timing when the start button is pressed, and the reel M3 is moved at a predetermined timing based on the determined stop table. Although the case where it stops automatically is demonstrated, it is not limited to this. Specifically, the slot machine 10 has a reel stop button (not shown) corresponding to each reel M3, and one stop table among a plurality of stop tables is randomly determined when the operation button is pressed. The reel M3 may be configured to stop based on the determined stop table and the pressing timing of the reel stop button. That is, after the internal lottery of the stop table is performed, the slot machine 10 stops the reel M3 at the pressing timing of the internal lottery stop table and the reel stop button, and the symbol 501 when all the reels M3 are stopped. It may be configured to determine whether or not a prize is established based on the winning combination.

  FIG. 29 shows execution processing in the slot machine 10. When the power is supplied to the slot machine 10, the main CPU reads the program from the memory card 54 via the gaming board 50 and writes it to the RAM 73 to load the authenticated game program and game system program. (S400). Next, the main CP 71 executes a game program and a game system program.

  When a player starts an unit game by inserting an IC card into an IC card reader or inserting a coin into a coin insertion device, the unit game is newly executed based on the inserted coins or stored bets. it can. When the unit game is executed for the first time after the slot machine 10 is activated, the game mode becomes the normal mode. Thus, the main CP 71 executes the normal mode game process for the first unit game (S402).

  Each time the normal mode game ends, the game mode determination process P316 executed by the main CP 71 determines whether or not a trigger event has occurred (S404). Unless a trigger event occurs, the game mode of the subsequent unit game is maintained in the normal mode. Accordingly, the main CP 71 returns the process to step S402 and executes the normal mode game process for the subsequent unit game.

  However, if the main CP 71 determines that the trigger event has occurred in the determination process in step S404, the main CP 71 changes the game mode of the subsequent unit game to the chance mode.

  As described above, in the preferred embodiment, the number of unit games in the chance mode that can be executed in a single session is eight. The symbol code determination tables 341 to 348 are different from each other and can be used for each unit game in the chance mode. As each unit game in the chance mode is executed, the game counter increases the number of unit games already executed in the session or decreases the number of unit games remaining in the session. In the following, it is assumed that the game counter increases the number of unit games already executed from zero. Accordingly, in the process of step S406, the main CP 71 sets the game counter to zero. Thereafter, the main CP 71 executes a chance mode game process for the subsequent game (S408).

  Each time the unit game in the chance mode ends, the game mode determination process P316 determines whether or not the end condition is satisfied (S409). Unless the end condition is satisfied, the game mode of the subsequent unit game is maintained in the chance mode. Therefore, the main CP 71 returns the process to step S408, and executes the chance mode game process for the subsequent unit game.

  When the main CP 71 determines that the end condition is satisfied in the determination processing in step S409, the main CP 71 returns the game mode of the subsequent unit game to the normal mode. Accordingly, the main CP 71 returns the process to step S402 and executes the normal mode game process for the subsequent unit game.

  FIG. 30 shows normal mode execution processing, and shows step S402 shown in FIG. 29 in detail.

  The main CP 71 executes a memory initialization process every time the unit game ends (S410). In this initialization process, the main CP 71 clears unnecessary data and information from the temporary work area of the RAM 73. Unnecessary data and information include, for example, payout data, winning / losing information, and scheduled stop symbol information determined in the previous unit game.

  Thereafter, the main CP 71 executes a coin insertion / start check process (S412). In this process, the main CP 71 checks the insertion of coins and bills, and scans input from the BET button and the START button.

  After the START button [spin button] is pressed by the player, the main CP 71 executes symbol determination processing (S414). In this process, the main CP 71 generates five random numbers, and refers to the symbol code determination table 340 to determine five symbol codes of the five scheduled symbols according to the random numbers. The main CP 71 determines whether or not a winning combination is established based on a symbol matrix formed by the rearranged symbols.

  In step S416, the main CP 71 executes a symbol display control process. In this process, the main CP 71 controls the reel device M1, rotates each reel M3 of the first to fifth reel assemblies M11a to M11e, and then rearranges and displays symbols according to the result of the symbol determination process. In order to form a symbol matrix in the window 150, each reel M3 is stopped.

  Next, in step S418, the main CP 71 determines a payout amount, and executes a payout process in order to give the determined payout amount to the player.

(Symbol determination processing)
FIG. 31 shows the symbol determination process and shows step S414 of FIG. 30 in detail.

  First, the random number generation process P302 executed by the main CP 71 extracts five random numbers (S450).

  Thereafter, the symbol determination process P304 executed by the main CP 71 refers to the symbol code determination table 340 using each of the first to fifth random numbers to determine the first to fifth symbol codes (S452). Next, as shown in FIG. 20, the main CP 71 refers to the symbol code table using each of the first to fifth symbol codes, and determines the corresponding first to fifth symbols to be stopped (S454). ). As a result, the five symbols to be stopped are determined by using five random numbers. By determining the first to fifth symbols to be stopped, the main CP 71 stores the symbols or symbol codes in the RAM 73.

  The five symbols to be stopped are symbols that are stopped in the second row of each column of the symbol matrix shown in FIG. Since the arrangement of the symbols constituting the first to fifth symbol columns is fixed in correspondence with each of the reels M3 of the first to fifth reel assemblies M11a to M11e, the symbols to be stopped are determined. All symbols constituting the symbol matrix are determined. The main CP 71 refers to the symbol code table of FIG. 20 and determines all symbols constituting the symbol matrix based on the symbols to be stopped (S456).

  Thereafter, the winning determination process P310 executed by the main CP 71 determines whether or not a winning combination is established by the symbols constituting the symbol matrix determined by the process of step S456 (S458). When a winning combination is established by the symbols constituting the symbol matrix, the winning determination process P310 stores the winning combination in the RAM 73. Further, the main CP 71 may determine whether or not a winning combination has been established from the symbol code of the symbol to be stopped without determining whether or not a winning combination has been established using the symbol matrix.

  Finally, the symbol determination process ends, and the execution flow returns to the main process (not shown). Then, a symbol display control process is executed to rotate the reels M3 of the first to fifth reel assemblies M11a to M11e. The reels M3 of the first to fifth reel assemblies M11a to M11e rotate at mutually different speeds, and the symbol columns attached to the reels M3 are scrolled by the display window 150 of the reel device M1. While each reel M3 is rotating, the backlight device M7 is operated to produce an effect from behind the reel band M32. Thereafter, the reels M3 of the first to fifth reel assemblies M11a to M11e are stopped. In this way, the scrolling of the symbol column is stopped so that the stop scheduled symbol is located in the second row of the symbol matrix formed in the display window 150.

  When the symbol display control process ends, the process returns to the main process. Then, a payout process is executed. That is, when a winning combination is established, a payout amount corresponding to the winning combination is determined, and the determined amount is paid out by increasing credits or discharging coins.

(Chance mode execution process)
FIGS. 32 and 33 show a chance mode game process (S408) as well as an end condition determination process (S409) as shown in detail in FIG.

  When shifting to the chance mode, first, the main CP 71 executes a memory initialization process (S510). The main CP 71 clears unnecessary data and information from the temporary work area of the RAM 73. Unnecessary data and information include, for example, payout data, winning / losing information, and scheduled stop symbol information determined in the previous unit game.

  Next, in step S511, the main CP 71 increases the count value of the game counter indicating the serial number of the chance mode game to be executed. Since the count value of the game counter is initialized to 0, the count value of the game counter is set to 1 in the first (first) chance mode game.

  Thereafter, the main CP 71 executes a coin insertion / start check process (S512). In this process, the main CP 71 checks the insertion of coins and bills, and detects input signals from the BET button and the START button.

  The main CP 71 executes symbol determination processing after the START button is pressed by the player (S514). In this process, the main CP 71 first generates five random numbers. Next, the symbol determination process P304 executed by the main CP 71 uses the first to fifth random numbers to refer to any of the symbol code determination tables 341 to 348, respectively, to thereby determine the first to fifth symbols. Determine the code. When the first (first) chance mode game is being executed, the symbol code determination table 341 is used to determine the symbol code. When the second chance mode game is being executed, the symbol code determination table 342 is used to determine the symbol code. Similarly, when another chance mode game is being executed, one of the symbol code determination tables 343 to 348 is used for determining the symbol code according to the order.

  Thereafter, the main CP 71 determines the first to fifth symbols to be stopped corresponding to the first to fifth symbol codes with reference to the symbol code table shown in FIG. As a result, five symbols to be stopped are determined by using five random numbers. When determining the first to fifth stop scheduled symbols, the main CP 71 stores the symbols or symbol codes in the RAM 73.

  Next, the winning determination process P310 executed by the main CP 71 determines whether or not a predetermined winning combination is established by the rearranged symbols. When a predetermined winning combination is established by the rearranged symbols, the winning determination process P310 stores the winning combination in the RAM 73.

  The main CP 71 checks whether or not the value of the game count 324 has reached 8 (S516). The value of the game count 324 is a number indicating that the last (eighth) chance mode game is being executed. If it is determined that the game count value has reached 8, the main CP 71 determines whether or not the end condition is satisfied (S518). One of the end conditions is that one of the winning combinations composed of “7” symbols is established. Another termination condition is that the “cherry” symbol of the symbol matrix formed by the rearranged symbols appears on one of the paylines.

  When the value of the game count 324 reaches 8 and one of the winning combinations composed of “7” symbols is not established, or the “cherry” symbol of the symbol matrix formed by the rearranged symbols is 1 on the payline. If it does not appear, the main CP 71 returns the process to step S514 and executes the process of step S514 again. As described above, in the process of step S518, one of the winning combinations including “7” symbols is established, or the “cherry” symbol of the symbol matrix formed by the rearranged symbols is set as one payline. It can appear.

  On the other hand, when it is determined in step S516 that the value of the game count 324 has not reached 8, or when one of the winning combinations composed of “7” symbols is established in step S518, or If the “cherry” symbol of the symbol matrix formed by the arranged symbols appears on one of the paylines, the process proceeds to step S520.

  The main CP 71 controls the reel device M1 and executes a symbol display control process so as to stop the rotation of the reel M3 of the first to fifth reel assemblies M11a to M11e (S520). Symbol scrolling is stopped according to the result of the symbol determination process, the symbols are rearranged, and a symbol matrix is formed in the display window 150. The main CP 71 executes a payout process, determines the payout amount, and provides the determined payout amount to the player (S522).

  The main CP 71 determines again whether or not the end condition is satisfied (S524). If the end condition is satisfied, the main CP 71 ends the chance mode playing process. If it is determined in step S524 that the end condition is not satisfied, the process returns to step S511, the value of the game count 324 is increased, the chance mode is continued, and the unit game in the next chance mode is played. Run.

  As described above, the chance mode game continues until a winning combination including the “7” symbol or the “cherry” symbol appears on at least one of the paylines LINE1 to LINE5. Further, when the chance mode game is executed up to a predetermined maximum number of times, the main CP 71 can reliably satisfy the end condition.

  In a preferred embodiment, the probability that a winning combination constituted by “7” symbols appears in the chance mode is larger than the probability in the normal mode. Specifically, as the chance mode continues, the probability that a winning combination composed of “7” symbols appears gradually increases. Further, the probability is 100% in the eighth chance mode game. On the other hand, the probability of other winning combinations may be lowered to some extent as compared with the probability in the normal mode. Furthermore, it is preferable that all paylines LINE1 to LINE5 are activated regardless of the bet amount.

  As described above, when the chance mode game is executed, as shown in FIG. 17, a transparent symbol display state in which the transparent symbol M332 is visually recognized in an area other than the area where the symbol 501 is displayed is set. In other words, in the normal mode that is not the chance mode game, the transparent symbol M332 is in a state where the transparent symbol M332 is hardly visible. In this way, by visually recognizing the transparent symbol M332, it is notified that the game mode is the chance mode.

  In addition, it may be notified that the game mode is the chance mode by an image and / or sound effect. In addition, the chance mode may be notified in such a manner that the backlight of the backlight device M7 is made brighter or darker than the normal mode, the sound at the time of operating the start button is made high, the reel stop sound is You may alert | report in the aspect which shortens an interval.

(Irradiation control processing)
With reference to the irradiation control routine of FIG. 34, the irradiation control process which alert | reports the classification of game mode is demonstrated. First, the type of game mode currently in progress is acquired (S811). Subsequently, it is determined whether or not the game mode is the normal mode (S812). If it is in the normal mode (S812: YES), the irradiation light of the backlight device M7 is turned off (S813) so that the display mode of the display window 150 in the non-transparent symbol display state indicating the normal mode. As a result, as shown in FIG. 16, the internal space M333 is darker than the outside of the reel device M1, so that the transparent symbol M332 is hardly visible. If the normal mode is already set before step S812, the process may be skipped. Thereafter, this routine is terminated.

  On the other hand, if it is not the normal mode in step S823 (S812: NO), the illumination light of the backlight device M7 is turned on so that the display mode of the transmission symbol display state indicating the chance mode is displayed on the display window 150 (S814). ). As a result, as shown in FIG. 17, the internal space M333 becomes brighter than the outside of the reel device M1, so that the transparent symbol M332 is easily visible. If the chance mode has already been set before step S812, the processing may be skipped. Thereafter, this routine is terminated.

  Further, the irradiation control process may be executed by the irradiation control routine of FIG. That is, first, it is determined whether or not the transparent symbol display condition is satisfied (S801). In the present embodiment, the transparent symbol display condition is that the game mode has shifted to the chance mode. That is, in the determination of the trigger event occurrence in step S404 described with reference to FIG. 29, the transparent symbol display condition is satisfied when it is determined that the trigger event has occurred. When the transparent symbol display condition is not satisfied, that is, when the chance mode is not set (S801: NO), the routine is terminated and the routine is restarted at the next predetermined timing, whereby the determination in S801 is repeated.

  As a result, during the period when the transparent symbol display condition is not satisfied (the period when the chance mode is not set), the free game and the basic game are executed in the transparent symbol display state. It will be. The irradiation start condition can be exemplified by a case where a predetermined prize is established or a predetermined type of game is started in addition to the period in the chance mode.

  On the other hand, when the transparent symbol display condition is satisfied, that is, when the chance mode is set (S801: YES), the backlight device M7 is set to display the transparent symbol display state indicating the chance mode in the display window 150. The irradiation light is turned on (S802).

  Accordingly, the player can recognize that the current game is in the chance mode by visually recognizing the transparent symbol M332 displayed on the display window 150. Thereafter, it is determined whether or not the transparent symbol non-display condition is satisfied (S804: NO). In the present embodiment, the transparent symbol non-display condition is that the chance mode has ended. That is, the transparent symbol non-display condition is satisfied when it is determined that the end condition is satisfied in the determination of whether the end condition of step S409 described with reference to FIG. 29 is satisfied. When the transmission symbol display condition is not satisfied (S804: NO), the irradiation in S802 is continued. On the other hand, when the transparent symbol non-display condition is satisfied (S804: YES), the irradiation light of the backlight device M7 is turned off so as to set the display state in the transparent symbol non-display state in the display window 150 (S804). Thereafter, this routine is terminated.

As described above, when the transparent symbol is not displayed, the illumination light emitted from the backlight device M7 is irradiated with the same color or the same color as the color of the transparent symbol M332, and the transparent symbol is displayed. In order to make it difficult to visually recognize M332, in step S813 and step S804 described above, control for changing the color of the irradiation light of the backlight device M7 is performed.
Further, in the case where the light intensity of the outside illumination light from the irradiation light device R1 is made stronger than the inside illumination light of the backlight device M7 to make it difficult to visually recognize the transmission symbol M332, in step S813 and step S804 described above, Control to weaken the illumination light of the backlight device M7 or control to increase the illumination light of the irradiation light device R1 is performed.

  Here, the timing of the transparent symbol display state and the timing of the transparent symbol non-display state may be set individually for each rotation and stop of each reel M3, or for the rotation and stop of all the reels M3. It may be done. Furthermore, the transparent symbol display state may be set only when the reel M3 of the third reel assembly M11c is stopped.

  Further, for example, in the symbol display mode, the case where the timing of irradiation start and irradiation stop is set with respect to the rotation and stop of all the reels M3 will be described. A transparent symbol M332 can be displayed. In this case, the display on the display window 150 is changed after all the reels M3 are stopped. At this time, the display and non-display of the transmission symbol M332 can be repeated by alternately controlling the illumination light of the backlight device M7 to be turned off and on.

  The reason for changing the display of the display window 150 after all the reels M3 are stopped as described above is that when the display other than the symbol 501 is changed in the display window 150 during the rotation of the reel M3, the symbol 501 becomes difficult to see. Because of the reason.
